I manage watcher callables for STDOUT and STDERR.

You can call my run_out and run_err methods with a line of STDOUT or STDERR without worrying about a watcher being registered or unregistered during the process.

If a watcher is registered while others are being called for that same output type, it will get called, too, as long as it gets registered before the runner method finishes. And it will certainly get called the next time the runner method is called.

If a watcher is unregistered while others are being called for that same output type, it won't raise any errors. If it gets called before being unregistered, that will be the last time it ever is. If it gets unregistered before the runner method gets around to it, then it won't be called.

You can register and unregister a watcher as many times as you wish.
